Leaky bouyancy tanks

 

Hi all, I'm still having an issue with water getting in to the front bouyancy compartment. I've checked all the keelband screws and re-sealed them but it's still filling up. After some wild weather today it had loads in it. But with the hull dry afterwards nothing is coming back out. Anyone have any idea how the water is still getting in?

I also found water in the side tanks. My old boat is a pre-MD conversion but I have inspection hatches at the rear of the side tanks. Does anyone know if these are connected to the front compartment hence water getting in there, or are these leaking themselves somewhere??

As usual, any advice very gratefully appreciated.

The front tank is connected to the side tanks - it is all one big tank.

On mine there were cracks on the floor that were letting water through into the tank - especially on the port side where there wasn't much adhesive holding everything together. If you can see any cracks in the tank molding then worth grinding back a bit for adhesion and putting some epoxy and tape over the top.

It is often worth looking up rather than down?
You said that there was water ingress when it was raining.
If you have a mooring cleat or any other fixing in the foredeck it is worth checking these.Use a hose on particular places.You can lay newspaper prior to wetting the fore deck,damp patches may give you an idea of leak area.

Hi Jonathan
Check the GRP under and around the mast step and check that the screws are a good fit.? Any rain water collecting in this area can leak through directly to the buoyancy tank.

Thanks Mike and Douglas.

I don't think it will be the deck cleat as that still wouldn't get into the bouyancy tank - just fill up the bottom of the hull. Mast base is a distinct possibility, any rain on the mast runs right under the cover there so could be finding its way in. I suppose even a slight trickle over a week would end up with a lot of water.

Any idea if the side buoyancy tanks are connected to the front one? If so that would explain why there's water in there too! Otherwise I've got 3 leaks to track down!

Thank you for your help.
